Abstract
The present disclosure belongs to the technical field of functional films, and in particular relates to a self-lubricating film over wide temperature ranges in vacuum and a preparation method and use thereof. The present disclosure provides a self-lubricating film over wide temperature ranges in vacuum, including: a bonding layer, a transition layer and a lubricating layer laminated in sequence, wherein the bonding layer has a chemical composition of Ti; the transition layer has a chemical composition of Ti and TiB; the lubricating layer has a chemical composition of Ti, TiBand MoS. In the present disclosure, when the self-lubricating films over wide temperature ranges in vacuum are exposed to different temperatures, different components of Ti, TiBand MoSin the films may be correspondingly excited to enrich in frictional contact areas. The composition of each layer synergistically exerts a lubricating effect and improves the tribological properties and stability of the self-lubricating film over wide temperature ranges in vacuum in a vacuum over a wide temperature range.
